COMBINED DIE AND WHEEL REMOVER Filed March 6, 1930 Patented Aug. 25, 1931 WILLIAM GUYER FISHER, OF REDLANDS, CALIFORNIA OOIVIBINED DIE AND HE-EL REMOVER Application filed March 6,

My invention has for its object the provision of an extremely simple and highly efiicient combined die and'wheel' remover and, to this end, it consists of the novel construction and arrangement of parts hereinafter 1c axle spindle to remove the described and defined in the claim.

It is now quite the general practice of mechanics in removing a vehicle wheel from its screw-threaded main axle shaft or the front nut and pound on the end of the shaft or spindle to jar the wheel loose. For the sake of brevity the word spindle will hereinafter be used in a-broad sense to cover either a shaft or spindle. This pounding on the end of a spindle invariably forms a mushroom thereon or, at least, swells the same to such an extent as to make it dificult to apply the nut thereto when remounting the wheel. Certain types of wheel pullers now in use that are applied to the screw-threaded end of a spindle are also objectionable for the reason that they swell the end thereof and make it diificult to apply the nut thereto.

My combined die and wheel remover is formed from a single piece of tool steel having in one end a thread cutting die, on its other end a striking head and a spindle striking seat on the bottom of the die cavity. This device is adapted to be screwed onto the threaded end of a spindle until stopped by the engagement of the spindle seat with the end of the spindle. With the device thus applied, the head of the device is struck with a hammer with sufficient force and number of times to jar the wheel loose and the force of the blows will be transmitted through the device directly onto the end of the spindle longitudinally thereof and not on the screw threads.

In case the wheel is frozen or rusted on its spindle and'a great deal of pounding is re uired to loosen the same, the device is 'tig tened by screwing the same onto the spin- 5 dleafter every few blows to take up slack produced by the swelling of the threaded end of the spindle so that the force of all blows will be direct on the spindle.

The die not only affords convenient means for applying the device to a spindle but also 1930. Serial No. 433,645.

recuts the threads and reshapes the end of thespin'dle in case the same has been previously. distorted or the thread mutilated. "If the end of the spindle is expanded due to heavy pounding on the device, the thread will be reshaped by the device when turned in a direction to remove the same from the spindle. Furthermore, the die due to the heavy structure of the device therearound will hold and prevent the spindle from expanding beyond the size of the die due to pounding on the device.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view of the device;

Fig. 2 is a transverse section taken on the line 2-2 of Fig. l; and

Fig. 3 is a view partly in elevation and partly in section showing the device applied to a main axle shaft for the purpose of removing the wheel therefrom.

The numeral 4 indicates the hub portion of a vehicle Wheel mounted on a main rear axle shaft 5 having on its outer end a screwthread 6 by which a nut, not shown, is applied to said shaft for holding the wheel thereon.

The combined die and wheel remover is formed from a single piece of tool steel and includes a body 7 having a polygonal exterior. Said body 7 has in one end an axially located screw-thread cutting die 8, on the other end an axially aligned contracted striking head 9 and an axle shaft or spindle seat 10 on the bottom of the die cavity.

To remove the wheel from the axle 5 the nut is first removed from the threaded end thereof and the device applied thereto by screwing it thereon until stopped by the engagement of the seat 10 with the end of said shaft. In case the end of the shaft 5 has been expanded due to previous pounding or the thread 6 mutilated, the application of the device to theshaft 5 will cause the die 8 to cut and reshape the end of the shaft 5 and thread 6. When it is difficult to turn the device on the shaft 5 by hand a wrench may be applied to the polygonal surface thereof.

Formed in the body 7 is a multiplicity of radial passageways 11 which lead from the bottom of the die cavity to the exterior of said body for the escape of shavings cut by the die. After applying the device to a spindle that has been badly bruised due to pounding it'is advisable to retract the device, before actual pounding thereon is started, and removeany shavings therein so that the seat 10 will impinge directly against the end of the spindle.

What I claim is:

A device comprising a combined die and wheel remover, a tapered metal body providing a striking head and having a socket for engaging a threaded axle end, said socket being internally threaded and havinga plurality of longitudinally extending spaced grooves dividing the socket into a number of thread cutting surfaces, said die and Wheel remover further having intermediate the ends thereof a plurality of radially extending apertures, each aperture directly communieating witha groove, whereby the socket may be thoroughly cleaned of steel cuttings without removing the device from the axle end.

In testimony whereof I aflix my signature.

WILLIAM GUYER FISHER.
